How does an inertia-free hammer work?
Nowadays, all kinds of devices and mechanisms are constantly being improved. And if this does not surprise anyone in the field of electronics, then changes in the design of simple tools known to everyone may be unexpected. So tool shop https://moi-instrumenty. ru/ offers to buy an inertia-free hammer. How does it work and what are its advantages?
Operating principle of inertia-free percussion instruments
When an ordinary hammer hits a hard surface, a recoil phenomenon is observed. According to the law of conservation of momentum, after contact with the surface, the tool head begins to move in the opposite direction. The master feels a blow on his hand. This phenomenon reduces the accuracy of hammering and can be harmful to human health, since repeated recoil negatively affects the ligaments of the hand.
An inertia-free hammer has a hollow head, inside of which there is a loose filler. These are usually small metal balls. Balls fill 3/4 of the internal space of the head, which allows them to flow freely. If the hammer moves down to strike, the balls move with it in the same direction. After the impact, some of the balls continue to move downward by inertia. With their movement they slow down those that have already bounced off and are heading upward, creating recoil. The friction between these streams of balls slows down and dampens their movement. This reduces the recoil of the hammer.
Inertia-free hammers are successfully used for various types of work. They are especially in demand in auto repair shops, since the master often has to strike in a limited space, and there is simply no room for the hammer to bounce back.
Using modern tools increases productivity and safety.
